Answer 1

maybe something like this:

$numRow= mysql_num_rows($followup_details)

and in your loop:

 <td>
<?php if($slno >= $numRow) { ?>
  <a href="#" class="edit-followup" data-reveal-id="editfollowup" data-animation="fade" id="<?php echo $followup['followup_id'];?>"><img src="images/edit_icon.png" alt="editicon" width="20" height="20" border="0" class="marg" /></a>
<?php } ?>
</td>

Answer 2

Maybe You can print the edit buttons after you have generated the list, so it is not in the loop, but follows directly afterwards. Or you can check the number of rows before the loop. Then in the loop you put a counter from 1. When the counter is equal to the number of rows, you print the buttons.

Answer 3

First, you can get total no of records before while loop

  $total_records = mysql_num_rows($followup_details);

Now check in while loop

if($slno == $total_records -1 )
{
  ?>
    // this is final record
<a href="#" class="edit-followup" data-reveal-id="editfollowup" data-animation="fade" id="<?php echo $followup['followup_id'];?>"><img src="images/edit_icon.png" alt="editicon" width="20" height="20" border="0" class="marg" /></a>
  <?php
 }else{
   echo "&nbsp;";
 }

Answer 4

Just add a check for $slno is 1. Because you are fetching records on descending order on followup_id so last inserted record will be on top (the first one).

<td>
  <?php
  if($slno===1):
  ?>
  <a href="#" class="edit-followup" data-reveal-id="editfollowup" data-animation="fade" id="<?php echo $followup['followup_id'];?>"><img src="images/edit_icon.png" alt="editicon" width="20" height="20" border="0" class="marg" /></a>
  <?php
  endif;
  ?>
